Here we go!  Let the ideas flow!

give mines a specific cloaking ability and reserve the others for ships...the AI would have a hard time with it.
So, what kinds of things would each of the other cloak/sensor types do?
Psychic:  master computer gives a max level cloak (any crew aboard go into cryo-hibernation for cloak, so they don't spew brainwaves 

)
- all cloaking devices should have psychic cloak lev 1, so you 
NEED the computer to hide.
temporal:  an all-seeing, but much more expensive tech?  How could it be realistically/believably stopped?
active/passive:  how about active level "x" requires passive level "x-2" (to detect faint return signals) and/or long range sensor tech?  Different cloaks could be stronger VS active or stronger VS passive.
